EVDRE Performance Issue on MS 7.5

Dear Experts,

I need your help in an issue with EVDRE expansion on BPC7.5 MS which is taking around 30 minutes. The same report was working fine last period:

• Report is on YTD measure, application is periodic
• Two dimensions in row, one in column with memberset Bas expansion
• One row dimension has 10000 members.

We have done the following

ð  Optimize the Application

ð  Process the Dimensions

ð  IIS, COM+component, application, Server, Sendgovernor, BPC insight  restart

ð  Process Cubes from SQL –Application Services

ð  InApp property check removed

But the issue persists.

We want to understand the reason since the same report worked fine in previous period

System details:

BPC 7.5 MS SP5

SQL server 2005

Thanks,
